JPS6443888A - Optical memory device - Google Patents

Abstract

PURPOSE:To prevent the raising of a temperature in a device, and to stably perform the recording and the reproducing of information by providing a ventilation hole at a cassette case inserting opening side, and forming an air path to the ventilation hole through the back of a cassette case. CONSTITUTION:When the cassette 2 is loaded in an optical memory device 1 and is in the state of 2B, that is, the working state, the cassette inserting opening 2 is in an open state, and a ventilation between the inside of the optical memory device 1 and an external part is possible through the inserting opening 3. Here, a fan is provided in an air stream that air outside the device is made to flow in from the inserting opening and is made to pass through the back of the case 2 and is exhausted from the ventilation hole 4 through the lower part of the case 2, and is driven by a motor. At this time, warm air around the case 2 generated during the working time of the optical memory device 1 is exhausted outside the device from the ventilation hole 4 and the raising of temperature in the optical memory device 1 can be prevented. Accordingly, the information can be stably recorded and reproduced.
