The present invention provides a touch panel input device that reliably prevents degradation of a piezoelectric substrate. During inactive periods in which a touch panel input device is not used, the connection between a set of output terminals of an AC power supply circuit and a set of associated drive electrodes on the piezoelectric substrate is switched with a selector switch so that the drive electrodes are shorted. During inactive periods, no DC potential is applied to the set of drive electrodes even if a charged conductive body comes into contact with the drive electrodes or a drive power source pattern connected thereto. This makes it possible to prevent the degradation of the piezoelectric substrate.

Provided is a control panel support mechanism having a first support member attached to an image forming apparatus, a second support member supporting a control panel and axially supported by the first support member to be vertically swingable with respect to the first support member, a lock member slidable towards or away from a swing axis of the second support member, and a biasing unit to bias the lock member to slide towards the swing axis. The first support member has a plurality of engaging grooves each positioned along a radial direction with respect to the swing axis and having an opening at an end of the first support member opposite the swing axis, the plurality of engaging grooves being aligned vertically. The biasing unit biases the lock member so that the lock member enters one of the plurality of engaging grooves through the opening to lock in engagement with the engaging groove.

A blower fan including an impeller easily mounted on the rotational shaft of a motor generates less noise. The impeller is mounted on the rotational shaft of the motor using a fastener with an elastic vibration isolator and a washer in between. The washer has a predetermined shape including radial projections from a circumference about a central receiving hole. The vibration isolator has the predetermined shape larger than the predetermined shape of the washer, and has a first recess having the predetermined shape on its top surface to receive the washer fittingly. The impeller has a second recess having the predetermined shape on its top surface to receive the vibration isolator fittingly. The vibration isolator thus separates the impeller mounted on the rotational shaft from the washer in both the axial and rotational directions of the motor to reduce vibrations in both directions propagating to the impeller, generating less noise.
