[Detailed explanation of the device]

[Í existing important point] The magnetic bubble memory cassette which contained the magnetic bubble memory device about the magnetic bubble memory cassette device used as external storages, such as a computer terminal device, for the purpose of expansion of the assurance temperature of magnetic bubble memory of operation, While forming a heat conduction board in the above-mentioned magnetic bubble memory cassette in the magnetic bubble memory cassette device which equips with the magnetic bubble memory cassette, and consists of a cassette holder which can be driven, In the above-mentioned cassette holder, when it equips with the above-mentioned magnetic bubble memory cassette, the heat conduction board of the magnetic bubble memory cassette is contacted, and it constitutes so that the heat conduction board which can perform heat dissipation or heating may be formed. [Industrial Application] This design is related with the magnetic bubble memory cassette device used as external storages, such as a computer terminal device. A magnetic bubble memory device is fixity, and f About reliability of a mechanically moving part is high, and it is used as external storages, such as a computer terminal device. It is operating in this magnetic bubble memory device (a saturation temperature does the about +40 degreeC rise of the chip temperature in the heat which occurs in that under access, especially a device to ambient air temperature.). Since the chip temperature of a device also rises so that ambient air temperature becomes high temperature, the temperature range which can operate a bubble memory is restricted by ambient air temperature. The types of the product which carries a bubble memory device are roughly classified into two kinds, a board type and a cassette type. One board type takes means to attach a fan outside, to send a wind and to radiate heat in an air cooling with blower, about processing of the heat which the bubble memory device generated, and he is trying to satisfy the assurance temperature (Ta=O~50degreeC) of a bubble memory of operation, as shown in Drawing 4. A bubble memory device is [ cassette type of another side ] contained in a cassette. there is a drive (a cassette holder is called below) for operating a cassette independently -- a cassette -- all the cassette itself -- since it is a system which is stored in a cassette holder and performs data transfer, As hatching was put in and shown in Drawing 4 which can send a wind and can be cooled from the exterior like a board type, a guarantee range of operation becomes narrow. However, the assurance temperature range of operation equivalent to a board type is required. [Description of the Prior Art] As the conventional magnetic bubble memory cassette device is shown in Drawing 5, it consists of cassette 1 and cassette holder 2, and cassette holder 2 is with controller part 3, A controller circuit to provide linear part 4, and holder part 5 and internal electrical power source part 6, and for controller part 3 operate a bubble to Universal, It comprises an interface circuit and linear part 4 comprises fan Kunyond Reicha for driving a cassette directly, coiled Leiber, a sense amplifier, etc., and holder part 5 has a mechanism part which inserts cassette 1, and has support Be able to structure enough in inserted Cassette 7. Drawings 6 are an outline drawing of the conventional magnetic bubble memory cassette device, and a figure showing a section [ in / in Drawing 7 / (a) VII-VII line of Drawing 6 ]. The magnetic bubble memory device by which I is a cassette, 2 is a cassette holder, and 1a was built in the cassette in both figures, A lid and 9 are [ component-mounting parts 13 of each print board of the print board of a linear part and 11 ] interface connectors the print board of a power supply section, and 12 the print board of a controller part, and 10 the connector for cassette connection provided in the cassette holder 7, and 8. As for cassette l, in such a magnetic bubble memory cassette device, the design of the miniaturization of case size and slimming down is made by miniaturization thought. [Problem(s) to be Solved by the Device] the above-mentioned conventional magnetic bubble memory cassette did not have enough consideration It is about heat dissipation processing of the heat which occurs out of the pursuit to a miniaturization. Therefore, the heat of the bubble memory device which arises while accessing a cassette is received, If it goes up to temperature with the case temperature of a device and a fixed temperature is reached, the temperature detector (Sir Missri) built in the cassette will tell to a cassette holder, When a cassette was accessing, access was stopped, and the controller circuit part in a cassette holder was controlling in the non-accessing state again so that access became improper. However, the time of a cassette when the heat rise of a device becomes high temperature at, so that early and operation duty is high because of seal, and the temperature detector operates to reach to temperature is early. Therefore, the problem that it had to be interrupted or had to restrain duty of operation to ambient air temperature for a long time during data transfer was produced. the board type and cassette type assurance temperature range of operation which uses the bubble memory device of the same specification (the temperature specification of a device simple substance is the same) in view of the problem of the above-mentioned former [ this design ] -- the level -- again It aims at providing the magnetic bubble memory cassette device of A[ with a built-in heat conduction board ] ' Rivalry which can improve on the level more than the present cassette. [The means of Need which solves a subject] In order to achieve the above-mentioned [object, it is a magnetic bubble memory cassette device of this design, In the magnetic bubble memory cassette device which equips with magnetic bubble memory cassette 1 which contained the magnetic bubble memory device, and the magnetic bubble memory cassette 1, and consists of cassette holder 2 which can be driven, Heat conduction board 20 is formed in the above-mentioned magnetic bubble memory cassette 1, and it is in the above-mentioned cassette holder 2, When it equips with the above-mentioned magnetic bubble memory cassette, heat conduction board 20 of the magnetic bubble memory cassette 1 is contacted, heat conduction board 21 which can perform heat dissipation or heating is formed, and things are vF-fine-When(ed). [Function] Heat conduction board 20 is formed in cassette 1, and heat conduction board 21 is formed in cassette holder 2, respectively, When cassette 1 is connected to the cassette holder 2, and mutual heat conduction boards 21 and 20 contact simultaneously, heat can be radiated outside via heat conduction board 20.21 in the heat which occurred within cassette 1, By heating heat conduction board 21 of a cassette holder, the temperature in Cassette 7 can be raised and the guarantee range of operation of the magnetic bubble memory device in a cassette can be expanded. [Example] Drawing 1 is a sectional view showing the example of this design. In the figure, 1 is a cassette, 2 is a cassette holder, magnetic bubble memory device 1a is built in the cassette 1, and it is in cassette holder 2, It is the same as that of the conventional example explained in the 5~7th figure to provide connection Co non-Ri Tama, print board 9 of a controller part, print board 10 of a linear part, print board 11 of a power supply section, and the interface connector 13 grade, While the main point of this example takes and winds magnetic bubble memory device 1a around cassette 1 and forming heat conduction board 20, When heat conduction board 21 is formed also in cassette holder 2 and cassette 1 is inserted in the cassette holder 2, mutual heat conduction board 20.21 contacts and it can be made to perform conduction of heat. Exothermic resistors 22, such as a metalclad resistor, are attached to heat conduction board 21 formed in cassette holder 2. Drawings 2 and 3 are figures showing the cassette of the example of this design, and it is a sectional view [ in / Drawing 3<a> can set Drawing 2 in an exploded perspective view, can be set to an erection diagram, and / in Drawing 3 (b) / the b-b line of Drawing 3 (a) ]. In Drawing 2, 1a is a magnetic bubble memory device, and it was carried on substrate 31 with connector 30, and heat conduction board 20 which formed the perimeter cylindrical took and rolled it, and it has covered the perimeter with upper cover 32 and bottom cover 33 further. As shown in Drawing 3 (b), in order to make good heat conduction between magnetic bubble memory device 1a and heat conduction board 20, silicon rubber 34 is inserted among both, and it presses down from the outside, and is Press(ing) board 35. This control board 35 is bound tight with a driver etc. from the exterior of a cassette after assembly completion of a cassette. 36 uses non-heat-conducting characteristic material so that heat conduction board 20 may not be Heat transfer(ed) to a cover by the spacer for a top fixing to bottom cover 32.33. As this example constituted in this way is shown in Drawing 1, cassette 1 is inserted in the holder part of cassette holder 2, and heat conduction board 21 by the side of a cassette holder and heat conduction board 20 by the side of a cassette contact at the same time the connector between cassettes is connected with a cassette holder. The heat, as for, this occurs by operation of magnetic bubble memory device 1a radiates heat to the cassette holder exterior via heat conduction board 20 inside a cassette, and heat conduction board 21 of a cassette holder. When ambient air temperature is low, magnetic bubble memory device 1a in a cassette can be heated via heat conduction boards 21 and 20 by making exothermic resistor 22 provided in heat conduction board 21 by the side of a cassette holder generate heat. The chip temperature in a magnetic bubble memory device is raised by this, and the bubble memory operation with the degree of low temperature (outside of the conventional assurance temperature) is attained. [Effect of the Device] As explained above, according to this design, by the (b) high temperature side, access time can be kept long by heat distribution. (Ro) Since heat can be distributed more, the same guarantee range of operation as a board type is expectable, so that the volume of a heat conduction board is large. (C) At the low temperature side, access with the degree of low temperature is attained in the preheating operation from the cassette holder side by an exothermic resistor. It is size the place which can expect an operating temperature range wider than of operation assurance temperature range Ta=0~35-degreeC present cassette type by this, and can wait also for reduction of the duty restrictions of operation by the side of high temperature a term, comes, and contributes to the improvement in performance of a magnetic bubble memory cassette device.
