It is preferable that the blade replacement time detection unit and the blade replacement display unit constitute the power consumption unit. In this way, conventionally, only the electric pencil sharpener was provided,
The function of indicating that the blade for sharpening the pencil has reached the replacement time has been added to the manual pencil sharpener.

The power generation means generates AC power, and the blade replacement time detecting section has a counting section for counting the number of waves of the AC power, and the number of waves counted by the counting section is a predetermined value. , It is preferable that a signal indicating that the blade has reached the replacement time is output to the blade replacement display unit. In this way, the blade for sharpening the pencil has reached the replacement time without providing a measuring means for measuring the time for cutting the pencil or a counting means for counting the number of times the pencil has been cut. Since the detection can be performed, the entire configuration can be simplified even if the blade replacement time detection unit is provided.

If the angle is detected, the approximate length of the pulled-out tape 8 can be calculated based on the detected rotation angle, and the length can be displayed on the liquid crystal display panel 6.

In applying the present invention to the correction tape holder, as shown in FIG. 9, the rotational driving force applied to the reel 9A of the correction tape holder 1B is changed to a power generation means.
When the number of revolutions of the reel 9A is calculated from the counted number, the tape 9 is used up. It can be detected that the time is approaching, and it is determined that the tape 9 replacement time is approaching.
The user can be notified by lighting the ED9B.

Further, the power storage means is not limited to a secondary battery, but may be a capacitor.

Further, the dust amount detecting section is not limited to the pair of light emitting elements and light receiving elements, but a plurality of sets of light emitting elements and light receiving elements are provided at different height levels of the chip case, respectively. In addition, a level meter for displaying the height level of the chips accumulated in the chip case may be provided.

Further, the pencil sharpener with the generator has an LED
A light emitting element such as If such a light emitting element is provided instead of the liquid crystal display panel, various displays can be performed. Alternatively, if provided as an illumination separately from the liquid crystal display panel, the pencil sharpener can be decorated with illumination.

Further, the integrated circuit is not limited to one that forms a microcomputer for performing control or the like, and stores at least one of a predetermined music and voice and an electric circuit corresponding to the stored music and voice. A sound output IC capable of sequentially outputting signals, a sound signal such as an input sound is stored, a recording IC that sequentially outputs the stored sound signals, a clock that displays time, or a clock from a certain point in time. A clock IC such as a timer for displaying the elapsed time and a radio IC for receiving a radio broadcast may be provided. IC with such functions
Is provided as an integrated circuit, the function of the stationery is changed from a single function to a multi-function, the convenience is enhanced, and the added value of the stationery can be significantly improved. For example, if a pencil sharpener with a generator is provided with an audio output IC, the voice or music of a predetermined character can be heard during the work of sharpening a pencil. If a recording IC is provided in a stationery with a generator, a simple memo can be stored by voice.

Further, a stationery with a generator is provided with a timekeeping IC.
If a radio or radio IC is provided, a clock function and a radio function can be added.
