is a housing of a recording/reproducing device such as a VTR, 2 is a board of the device, 3 is a cylinder with a built-in magnetic head fixed to the board 2, and 4 is a heater, which is fixed to the cylinder 3 in this embodiment. However, it may also be fixed to the substrate 2 or to any other effective location of the device. Reference numeral 5 denotes a first switch that is made conductive in conjunction with the starting operation key of the vehicle, and when the operation key is in the operating state, the first switch 5 is also turned on. 6 is a battery, 7 is a temperature detection section in the device,
8 is a control unit that controls the operating mode of the device, 9 is an electromagnetic mechanism converter (solenoid), 1o is rotatably held on the board 2, and the other is provided in the cassette insertion port 12 of the housing 10. It is a lever connected to the shutter 11 that opens and closes the insertion port, and further connected to the electromagnetic mechanism converter 9 described above at an intermediate portion thereof. 13 indicates the position of the shutter 11 when the electromagnetic mechanism converter 9 attracts the operating lever 1o. Reference numeral 14 is a return spring (as described above)'-10. Next, the operation will be explained. When the starting operation key of the car is activated and the engine is started, the first switch 5 linked to the starting operation key is turned on, and the heater 4 installed in the device is turned on.
is energized, the cylinder 3 and the board 2 are heated, and the housing 1
The internal temperature of increases. On the other hand, when the temperature inside the housing 1 is detected by the temperature detection section 7, and this temperature is lower than the preset temperature, the operation of the control section 8 is turned OFF, and although not shown, the FB, REW/FF etc. does not accept operation mode switch signals.
また、カセット挿入口１２のシャッター１１は閉じた壕
まで装置の内外の空気流出入は阻止される。Further, the shutter 11 of the cassette insertion port 12 is closed to prevent air from flowing into and out of the apparatus.

ことがない。Therefore, even if the temperature inside the car rises rapidly due to an air conditioner or the like, there will be no temperature difference between the air temperature inside the device and the mechanical parts such as the cylinder 3, and no condensation will occur inside the device. As time passes, the device is heated by the heater 4 or by temperature transfer from outside the device. Then, the temperature detection section 7 detects a predetermined temperature, and the control section 8 starts to operate normally. In this state, when the device 1 is operated by operating the opening/closing switch of the shutter 11 (not shown), the electromagnetic mechanism converter 9 operates and attracts the lever 1.
0 and move the shutter 11 to the 13 position. Then, the cassette can be inserted, and at this time, as a matter of course, the air inside the vehicle flows into and out of the device, but the temperature difference between the inside and outside of the device at this time is small, and no dew condensation occurs inside the device.
