An image forming device includes an image recording unit for recording an image on a recording sheet, an upper paper feed cassette storage unit arranged above the image recording unit, a lower paper feed cassette storage unit arranged below the image recording unit, a lower paper feed cassette stored in the lower paper feed cassette storage unit, and an upper paper feed cassette stored in the upper paper feed cassette storage unit. The upper paper feed cassette has a larger lateral length than that of the lower paper feed cassette.

Image forming device

An image processing device includes an image scanning unit, a first paper feed cassette, and an image recording unit. The image scanning unit scans a document placed on a document scanning surface, which defines a maximum document size. The first paper feed cassette accommodates recording paper of a size up to a first size, which is the same as the maximum document size. The image recording unit records an image on the recording paper. The maximum document size is defined by a scan maximum main scanning length and a scan maximum sub-scanning length that is preferably shorter than the scan maximum main scanning length. A record main scanning direction is parallel or substantially parallel to a long side of the recording paper of the first size accommodated in the first paper feed cassette. A scan main scanning direction is parallel or substantially parallel to the record main scanning direction.

Image processing device

An image forming device includes a device frame and a photoconductive drum. The device frame includes a driving device, a driving gear that transmits a driving force from the driving device, and an urging member that supports the driving gear in a manner capable of moving along a moving direction of a photoconductive drum and urges the driving gear in an opposite direction from a direction in which the photoconductive drum is inserted. The photoconductive drum is inserted in the device frame and includes a driven gear to be engaged with the driving gear.

An image recording device is equipped with both facsimile functions and copier functions. The image recording device is provided with an image scanning part that transports a document from a document sheet supply tray, scans an image on the document and discharges the document onto a document sheet outlet tray. The image recording device is also provided with a recording part that transports a recording sheet from a cassette unit, records an image on it and discharges the recording sheet on a recorded paper discharge tray. The recorded paper discharge tray is positioned at the uppermost part of the device. Below the recorded paper discharge tray, arranged are the document sheet supply tray, document sheet outlet tray, multi-purpose tray and the cassette unit. All the trays are confined within the width of the device. In other words, no trays project from the side of the device. The recorded paper in the recorded paper discharge tray is easily confirmed since the recorded paper discharge tray is at the top of the device.

Image recording device

A piezoelectric resonator has oscillating electrodes disposed on opposite major surfaces of a piezoelectric substrate, which oscillating electrodes are arranged so as to extend from respective opposite ends of the piezoelectric substrate to a central portion of the piezoelectric substrate so that the central portions of the oscillating electrodes overlap with each other, with the oscillating substrate sandwiched between the oscillating electrodes. Oscillation buffer materials are disposed on portions of the opposite major surfaces of the piezoelectric substrate, which portions are displaced by the third harmonic oscillation having a frequency which is substantially equal to about three times the resonance frequency of the piezoelectric substrate.

Piezoelectric resonator including oscillation buffer materials

In order to improve reliability in electrical connection between internal terminal electrodes and external electrodes in a chip-type piezoelectric-resonator which, protected with resin so as to be capable of surface mounting, a mother substrate is prepared comprising a piezoelectric substrate and a plurality of piezoelectric resonance elements formed thereon. Thick-film electrodes are formed so as to cover the terminal electrodes of the respective piezoelectric resonance elements. Thermosetting protective resin members are applied to cover both major surfaces of the mother substrate, which in turn is divided into individual piezoelectric resonance elements so that the thick-film electrodes are exposed on divided surfaces formed by dividing step. External electrodes are formed on the divided surfaces.
