A recording apparatus has an image scanner, which reciprocates along a main-scanning direction to read an original image and a recording head, which also reciprocates along the main scanning direction to record an image. To avoid slanting the recorded image by the reciprocating motion, the recording head has a plurality of recording elements which are aligned at a predetermined slanted angle to the subscanning direction of the recording head.

There is described a printing apparatus, particularly a label printer, which includes a switching mechanism operable in response to movement of the lid to permit operation of the printing apparatus only when the lid is closed. This can be combined with detection of the presence or absence of a cassette in a cassette receiving bay of the apparatus so that operation of the printing apparatus is permitted only in the presence of a cassette and with the lid in the closed position.

An Inertia Sensor with an oscillatory reed connectible upon actuation to reed protection circuitry, timing circuitry, AC switch circuitry, and power supply circuitry for turning on an electric typewriter upon actuation of the spacer bar and automatically turning off the typewriter after a predetermined time delay. Another embodiment discloses an impact sensor utilizing a vibration sensitive reed having a magnet thereon movable within a coil for creating an electromotive force for producing a signal which is amplified by amplifier circuitry, detected, and utilized to actuate timing circuitry and an on-off switch which is connected to a power supply.

A liquid discharge apparatus includes a holder, a pre-treatment head, a smoother, and a print head. The holder reciprocally moves while holding a recording medium. The pre-treatment head discharges a pre-treatment liquid onto a surface of the recording medium held by the holder. The smoother smooths the pre-treatment liquid, which is discharged onto the surface of the recording medium, along the surface of the recording medium by a movement of the holder. The print head discharges a printing liquid onto the surface of the recording medium with the pre-treatment liquid smoothed.

An interlock circuit comprises a plurality of semiconductor switching units electrically connected or connectable in series in a supply line, a plurality of control units electrically connected to the plurality of semiconductor switching units, and a trigger unit electrically connected to the plurality of control circuits. Each control unit activates or deactivates a corresponding semiconductor switching unit in response to trigger signal received from the trigger unit.
