The scanner has a body having a scanning unit, a display device, a keypad, a holding member holding together the display and the keypad, a mounting structure for mounting the holding member to the body, and a cable holder having a holding part for holding a plurality of cables and arranged in a floating state at one of the keypad and the display. The cable holder has two side walls and a bottom wall, with grooves at the tops of the side walls. Cables are arranged in the grooves and pressed by a part of the holding member when the holding member is attached to the display device and the keypad.

A light source module has a laser diode, and a circuit board. The circuit board includes the laser diode, a driver circuit for the laser diode, and a connector for receiving a power supply for driving the laser diode from an electric power source. A lens and an aperture shapes the laser beam emitted from the laser diode. A housing made of electrical insulating material contains the lens, the aperture and the circuit board except for a portion of the circuit board where the connector is mounted.

A bar code reader having two reading windows, i.e., a bottom window and a side window. An increased number of scanning lines are used for constituting scanning patterns for scanning bar codes, and the arrangement of the optical system is contrived to decrease the whole size of the bar code reader and, particularly, to decrease the depth of the bar code reader. A source of laser light, a splitter for splitting the laser beam emitted from the laser light source into two, a reflection mirror for transmitting one beam from the splitter to a polygon mirror, the polygon mirror which rotates to scan the incident laser beam, a mirror system for emitting the beam reflected by the polygon mirror through the reading window, and a focusing member for focusing the beam reflected by the bar code onto a detector that detects the beam reflected by the bar code, are arranged on the same line in the bar code reader. By using a concave mirror, furthermore, the beam reflected by the bar code is folded back to one detector. The light-receiving surface of another detector is faced downward to receive the beam reflected by the bar code through Fresnel lens and mirror, thereby to decrease the depth of the bar code reader. Furthermore, the beam passage from the reflection mirror goes through the lower surface of the polygon mirror intersecting the axis of rotation of the polygon mirror.

An arragement for mounting a housing to a table. A mounting member includes a first wall adapted to be inserted into a housing and a second wall connected to the first wall and adapted to be secured to the table. The housing includes a guide for guiding the first wall into the housing. A positioning tab is provided on the second wall parallel to the first wall.

A magnetic head is held by a side wall through a head fixing fitting so as to freely advance into and retreat from a card sliding groove. First and second head urging levers are swingably supported through a pin. In a standby state, the magnetic head is away from the card travel groove, and card engaging sections of the first and second head urging levers are staying in the card travel groove. When a magnetic card slides in a card sliding direction, the magnetic card makes contact with a card contact section to push the card contact section away from the card travel groove. This causes the first head urging lever to push out the magnetic head into the card travel groove so that the magnetic head makes contact with the magnetic card.

A display tilting apparatus includes a moving bracket that supports a display, a ratchet mechanism that controls pivoting of the moving bracket to a first direction, an anti-tilting mechanism that inhibits pivoting of the moving bracket to a second direction that is opposite of the first direction, and a fixed bracket that is pivotably connected to the moving bracket via a pivot axis. The anti-tilting mechanism includes a first anti-tilting member, and a second anti-tilting member that is mounted on the fixed bracket. The first anti-tilting member and the second anti-tilting member are mounted so as to make a physical contact to each other.
