Abstract

PURPOSE:To save the time for a user to wait every time said user supplies power and checks a hardware, by so arranging that said check of hardware is performed by comparison of a count value of the number of supplying times of power with a preset value. CONSTITUTION:Every time a power switch is turned on, a counter control unit 2 reads a count value stored in a nonvolatile memory 3, adding 1 to the count value and storing again in the memory 3. When the count value obtained from the counter control unit 2 becomes a predetermined value, a hardware check control unit 4 clears the count value and contents in the nonvolatile memory 3, and at the same time, it activates a hardware check unit 5 for checking the hardware. If the count value does not reach the predetermined value, the hardware check control unit 4 controls the hardware check unit 5 not to do checking of the hardware.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to printers.

[Conventional technology]

Conventionally, this type of printer has been designed to perform a hardware check every time the power is turned on.

[Problem to be solved by the invention]

Since the conventional printer described above performs a hardware check every time the printer is turned on, it has the disadvantage that the user has to wait for the hardware check to be completed every time after the power is turned on.

An object of the present invention is to provide a printer that solves the above problems.

[Means to solve the problem]

In order to achieve the above object, the printer according to the present invention includes a counter control unit that counts the number of times the power is turned on;
It has a nonvolatile memory that stores count values, and a hardware check control unit that compares the count value of the counter control unit with a set value to determine whether or not to perform a hardware check.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

1 is a power switch, 2 is a counter control unit that counts the number of times the power is turned on, 3 is a nonvolatile memory that stores the count value, 4 is a hardware check control unit that determines whether or not to perform a hardware check, and 5 is a hardware This is the wear check department.

Each time the power is turned on, the counter control section 2 reads out the count value stored in the non-volatile memory 3, adds 1 to the count value, and stores it in the non-volatile memory 3 again.

When the count value obtained from the counter control unit 2 reaches a certain value, the hardware check control unit 4 clears the count value and the contents of the non-volatile memory 3, and activates the hardware check unit 5 to perform a hardware check. Processing is performed, and if a certain value has not been reached, the hardware check is not performed.

〔Effect of the invention〕

As explained above, the present invention does not check the hardware every time the power is turned on, but performs the hardware check once every several times the power is turned on, so that the user can check the hardware every time the power is turned on. This has the effect that there is no need to wait for such a long time.
