Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to computer peripheral equipment such as a rotary head type magnetic recording/reproducing device or a disk device, or other various driving equipment, and in particular, to The present invention relates to drive equipment that can perform predetermined aging operations under environmental conditions.

[Conventional technology]

When manufacturing computer peripherals such as rotary head magnetic recording/reproducing devices and floppy disk drives, aging is performed for a predetermined period of time in an environment of predetermined temperature and humidity before shipping.

Conventionally, this aging operation is performed by connecting a peripheral device to a host device, such as a host computer, having a memory that sequentially stores predetermined operations, and performing the aging operation according to the contents programmed in the host device.

[Problem to be solved by the invention]

However, if peripheral devices are connected to host devices for aging as in the above conventional method, when the number of devices for aging increases, it becomes necessary to prepare a correspondingly large number of host devices. More equipment is required for aging, which increases costs.

The present invention solves the above-mentioned conventional problems by eliminating the need for a host device for aging and allowing the device itself to perform the specified aging operation, thereby reducing the number of host devices required for aging and reducing costs. The purpose is to provide a drive device that can reduce the amount of energy used.

[Means for Solving the Problems] The present invention provides a drive device that is provided with an operating mechanism section and a control section that issues a drive command to the operating mechanism section, wherein the control section performs a predetermined aging operation. The device is characterized in that it is provided with a memory that stores a program to run the program, and a switching device that executes the program.

Furthermore, in the above means, the switching means is a connecting member that short-circuits predetermined terminals of the connector for external connection.

[Operation j] In the above means, when a switching command is issued to the control unit by, for example, shorting the terminals of an external connection connector when aging the drive equipment, the control unit changes the aging mode stored in the memory. A program is executed, and the drive mechanism section performs a predetermined aging operation based on this program. In this way, since the aging operation can be performed by the device itself, there is no need to connect it to a host device such as a host computer, which simplifies the equipment required for aging and reduces costs.
